Spiral tube heat exchangers
Fully welded stainless steel design for high pressures and temperatures - structurally compensates large temperature differences.
- Robust, fully welded design for pressures up to 120 bar
- Temperature loads up to 400 °C
- Spiral tube design compensates differing thermal expansion of shell and tube
- Suitable for supercritical CO2 operation
The spiral tube heat exchanger essentially consists of a shell and a spiral tube bundle: the tubes are spirally bent and installed in the shell as a bundle. The units are manufactured entirely from stainless steel.
High pressures, high temperatures
The robust, fully welded design permits pressures up to 120 bar; temperature loads up to 400 °C are possible. Large temperature differences - and thus strongly differing thermal expansion between shell and tube - are optimally compensated by the spiral tube construction.
Fields of application
Typical applications include heating systems, refrigeration (including supercritical CO2 operation at up to 120 bar), heat exchange in industrial processes, and the chemical, food and pharmaceutical industries.
Frequently asked questions
Which pressures and temperatures are spiral tube heat exchangers suitable for?
Thanks to the robust, fully welded design, pressures up to 120 bar and temperature loads up to 400 °C are permissible.
Is the design suitable for CO2 refrigeration systems?
Yes, supercritical CO2 operation at pressures up to 120 bar is possible.
How does the design handle large temperature differences?
Large temperature differences cause strongly differing thermal expansion between shell and tube - the spiral tube design compensates this optimally.
